This HDMI over Cat.5e/6/7 transmitter and receiver kit is an excellent solution for extending uncompressed high-definition audio and video, as well as Ethernet and control, over a single Cat.5e/6/7 cable up to 100 meters. It provides multiple data and control interfaces, including IR, RS-232, and LAN connections.
This extender kit complies with advanced HDCP 2.2 and HDMI 2.0 standards and supports legacy HDCP 1.x and HDMI 1.x standards. Despite the 10Gbps bandwidth limitation of HDBaseT, 4K UHD HDMI video, including 4K@60Hz (4:4:4), can be processed and extended by subsampling the 4:4:4 color to 4:2:0 and reducing the bit depth when necessary.
In addition to video, data, and control, these units also feature useful audio functions. The Optical Audio Return (OAR) function supports the transmission of optical audio from the receiver side to the transmitter side for local playback. Also included is an audio insertion function, allowing stereo analog audio to be embedded into the HDMI output signal. Completing the feature set is robust EDID management, along with automatic HDBaseT clock extension and TMDS re-clocking support. The receiver (PD) is powered by 48V PoH provided by the transmitter (PSE), offering greater flexibility in different installation scenarios.
